step.
2. Erase, then retrieve DTCs. Turn ignition off. If DTC B1483 is retrieved, go to
next step. If DTC B1483 is not retrieved, an intermittent condition may exist.
3. Remove driver-side air bag module. See DRIVER
-SIDE AIR BAG
MODULE & CLOCKSPRING
under REMOVAL & INSTALLATION.
Disconnect driver-side air bag module connector C-305. See Fig. 30
. Connect
Load Resistor (MB991865) to upper clockspring connector using Load
Resistor Adapter (MB991866). Insert load resistor adapter leads into terminals
No. 3 (Yellow/Green wire) and No. 4 (Yellow/Black wire) of connector C-305.
See Fig. 31
. Connect negative battery cable. Erase, then retrieve DTCs. If
DTC B1483 is retrieved, go to next step. If DTC B1483 is not retrieved,
replace driver-side air bag module. Go to step 7 .
4. Disconnect negative battery cable. Disconnect lower clockspring connector C-
307. Connect load resistor and load resistor adapter to terminals No. 11
(Yellow/Blue wire) and No. 12 (Yellow/Violet wire) on harness-side of
connector C-307. See Fig. 32
. Reconnect negative battery cable. Erase, then
retrieve DTCs. If DTC B1483 is retrieved, replace clockspring. Go to step 7 . I
f
DTC B1483 is not retrieved, go to next step.
5. Disconnect negative battery cable. Disconnect clockspring connector C-307.
Disconnect SRS ECU connector. Release SRS ECU connector shorting bar
using a cable tie. Measure resistance between ground and SRS ECU terminal
No. 33 (Yellow/Blue wire) and No. 34 (Yellow/Violet wire). See Fig. 33
. If
resistance is not infinite at both terminals, go to next step. If resistance is
infinite at both terminals, reconnect components. Erase, then retrieve DTCs. If
DTC B1483 is retrieved, replace SRS ECU. Go to step 7 .
6. Replace wire harness between SRS ECU and clockspring. Go to next step.
7. Reconnect all SRS components. Activate air bag system. Using scan tool,
retrieve DTCs. If DTC B1483 is retrieved, go to step 1 . If DTC B1401 is not
retrieved, system is normal at this time.

CIRCUIT OPERATION This circuit judges the signals of each switch ("COAST/SET", "ACC/RES" and
"CANCEL") of the auto-cruise control switch. The PCM detects the state of the
auto-cruise control switch by sensing the voltages shown below.
When all switches are OFF: 4.7 - 5.3 volts When the "CRUISE" (MAIN) switch is "ON": 0 - 0.3 volts When the "COAST/SET" switch is ON: 2.1 - 2.7 volts When the "ACC/RES" switch is ON: 3.3 - 4.0 volts When the "CANCEL" switch is ON: 0.8 - 1.5 volts
DTC SET CONDITIONS Check condition
The CRUISE indicator light illuminates.
Judgement Criteria The "COAST/SET" or "ACC/RES" switch remains on for 60 seconds.
TROUBLESHOOTING HINTS (The most likely causes for this case:)
Malfunction of the auto-cruise control switch. Malfunction of the clock spring. Damaged harness or connector. Malfunction of the PCM.
DIAGNOSIS Required Special Tools:
MB991223: Harness Set MB991923: Power Plant ECU Check Harness MB991958: Scan Tool (MUT-III sub assembly)
MB991824: V.C.I.

2. Turn the ignition switch to the "ON" position.
3. Set scan tool MB991958 to data reading mode for auto-cruise control
system.
Item 03: Resume Switch.
When "ACC/RES" switch is at the "ON" position, the display on
scan tool MB991958 should be "ON". When "ACC/RES" switch is at the "OFF" position, the display
on scan tool MB991958 should be "OFF".
4. Turn the ignition switch to the "LOCK" (OFF) position.
5. Disconnect scan tool MB991958.
Q: Is the switch operating properly?
YES : Go to Step 17 .
NO : Go to Step 3.
STEP 3. Measure the power supply voltage at auto-cruise control switch
connector C-302 by backprobing.
1. Remove the air bag module (driver's side). (Refer to GROUP 52B, Air
Bag Modules and Clock Spring P.52B-567).
2. Connect the negative (-) battery cable.
3. Do not disconnect auto-cruise control switch connector C-302.

Q: Is the measured voltage between 4.7 and 5.3 volts?
YES : Go to Step 5.
NO : Go to Step 8 .
STEP 5. Check PCM connector B-18, intermediate connector C-31, auto-
cruise control switch connector C-302 and clock spring connectors C-303
and C-306 for loose, corroded or damaged terminals, or terminals pushed
back in the connector.
